sun light.
 Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for a long time. In case of large vari-
ations in temperature, allow the measuring tool to adjust to
the ambient temperature before putting it into operation.
In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
 Avoid heavy impact or falling of the measuring tool. Af-
ter heavy exterior impact on the measuring tool, an accura-
cy check should always be carried out before continuing to
work (see "Levelling Accuracy").
 Switch the measuring tool off during transport. When
switching off, the levelling unit, which can be damaged in
case of intense movement, is locked.
